Content Delivery Summit: Google Talks YouTube Views, Caching

Google continues to build out POPs worldwide to reach more than a billion viewers and handle more than 100 hours of content uploaded per minute


“Mobile makes up almost 40% of YouTube’s global watch time,” said Keith McCallion, Google’s technical program manager for peering and content delivery.

McCallion spoke on the topic of “Google’s Approach to Content Delivery” at the 2014 Content Delivery Summit taking place today at the New York Hilton Midtown. The session focused on ways that Google, specifically for YouTube content delivery, works with network operators to deliver content and services efficiently and cost-effectively and aims to deliver its services with high performance, high reliability, and low latency for users.

To understand the scale Google faces with YouTube, McCallion showed a number of statistics, such as the number of users (well above 1 billion) and hours of video uploaded every minute (100 hours per minute).

Delivering at this scale requires going beyond the typical solution, and McCallion emphasized Google’s commitment to increasing quality globally.

“We have a number of data centers around the world,” said McCallion. “We then have a large backbone, which we’ve spoken a bit more about in the last year, especially when it comes to SDN” or software-defined networking.

McCallion emphasized the fact that Google invests heavily in infrastructure and has increased its spend on infrastructure over the past few years.
